3 Claims. (Cl. 28o-33.44)

This invention relates to an improved trailer attachment particularly adapted for use with a two-wheeled manure spreader.

It is an aim of this invention to provide a trailer frame of simple construction adapted to be secured to a wagon body, provided with rear wheels, to support it and to connect it to a draft vehicle.

More particularly, it is an aim of this invention to provide an improved trailer attachment for manure spreader-s and farm wagon bodies generally of a simple rigid construction which may be readily secured to a wagon body supported by a pair of rear wheels and having means adapted to be readily secured to the rear end of a draft' vehicle and to be swivelly connected to the forward end of the body supporting the frame for attaching the wagon body to the draft vehicle.

Other objects and advantages of the invention will hereinafter become more fully apparent from.

the following description of the drawings, which illustrate a preferred form of the invention, and whereinz Figure 1 is a side elevational View of the device shown supporting a manure spreader and attached to a draft vehicle,

Figure 2 is a top plan view ofthe same,

Figure 3` is a top plan viewr ofthe trailer.- frame,

Figure 4 is a longitudinal. vertical central sec--y tional view taken on the line 4-4 of Figure. 3, and

Figures 5 and 6 are cross sectional views taken on the lines 5-5 and B--S respectivelyfofFigureV 3.

Referring more particularly to the drawings wherein like reference characters designate like or corresponding parts throughout the different views, I0 designates the rear end of any conventional type of draft vehicle, and I I a farm wagon body on the rear end of which is mounted a manure spreader mechanism I2 which is connected' to a pair of rear wheels I3, in any suitable li0 manner, the operation of the spreader being controlled by a conventional hand lever I4 connected to the spreader I2 by a. chain I5. 'Ihe wheels I3 besides operating the spreader I2 form the support for the rear end of the body II.

This invention includes the combination of an improved trailer hitch, designated generally I6, and a trailer frame, designated generally I1, which are swivelly connected to each other and to the draft vehicle I0 and wagon body II respectively. 'I'he trailer hitch I i as best seen in Figures 1 and 2, comprises a U-shaped member I8 having its opposite ends I9 offset upwardly and adapted to be secured by the fastenings 20 to any suitable part of the rear end of the draft vehicle I0, such as the rear axle housing 2|. A pair of diagonally disposed braces 22 are secured at their ends to the draft vehicle I0 and to the side bars 23 of the U-shaped member I8 to brace the intermediate portion 24 of the member I8, which is disposed to the rear of the draft vehicle III and paral- 5 lel to its axle housing 2l. An inverted channel bar 25 is secured to the portion 24 by the fastenings 26.

The trailer frame I1 comprises the corresponding obliquely disposed longitudinal side bars 21, 10 the forward converging ends 28, which are rectangular shaped in cross section, as seen invFlgures 5 and 6, and the rear diverging ends 29, which are angle shaped as seen in Figure 4. Side bars 21 are held in a spaced relationship to each 15 other by the spaced transverse braces 30 which are preferably angle shaped in cross section,'as best seen in Figure 4.

Frame I1 adjacent its forward ends, is" provided with the spaced uprights 3I, preferably formed of 20 angle ir u1, to which is secured a-supportingfmem ber 32, by means of the fastenings 33. As seenin Figure 2, member 32 at its upper end is elongated and has its opposite ends bent to engage theI op posite sides of the forward end ofi thewagon bodyv 25 II', said ends being secured to the body by means of the fastenings 34. Bars 21 at their rear or diverging ends are providedv with the upwardly extending supports 35 which are securedat their upper ends to the opposite sides of theI wagon 30 body II adjacent the wheels I3 by meansv of.; the fastenings 36 to combine with the members 3| and' 32 to support theA forward end and intermediate portion of the body I I.

The arcually shaped downwardly extending 35 members 31 which are secured to and extend beyond the diverging ends of the bars 21, are adapted. to be engaged by the chain I5 to hold said chain out of engagement with the axle of the wheels I3. Only' one of the operating levers vI4 40 and chains I5? have been shown, in Figure 1, since these parts are' of conventional structure, but a corresponding lever I4 and chain I5 would be mounted on the opposite side of the wagon Ill. 'I'he two levers I4 being used in conjunction to 45 control the operation of the manure spreader I2.

As best seen in Figures 4 and 6, the forward end of the frame I1 is provided with a transversely disposed bearing or wear plate 38, which is secured to the under side of the converging ends of 50 the side bars 21, and which is provided with a central opening 39. A wear plate or bearing 40 corresponding in dimensions to the plate 38 is adapted to be mounted on the channel member 25 intermediate the end of member 25 and portion 55 24, and is provided with an upwardly extending pin or shaft 4i adapted to extend through the opening 39 and to be journaled therein, and a downwardly extending threaded bolt I2 projecting through aligned openings I3 in portion 24 and member 23 and provided with a nut M on its free end to secure plate Il to channel member 2l.

From the foregoing it will be seen, that the frame Il combines with the wheels i3 to support the wagon Il, and is in turn supported by the hitch IB which is mounted on the rear end of the draft vehicle I0. The members 3i, 32 and 35 provide means whereby the frame I1 may be readily attached to support wagon II, and the braces 22 and fastenings 20 provide means for readily attaching or detaching hitch i3 to or from a draft vehicle I0. The weight of the forward end of the body Il will retain the wear plate 38 in engagement with wear plate I "when the pin 4i is in engagement with the opening 39, thereby providing an exceedingly simpliiled form of hitch connection between the draft and trailer vehicles permitting the trailerv vehicle to be disengaged by merely lifting it out of engagement with pin 4I. The abutting faces of wear plates 33 and 40 may be suitably lubricated so that the weight of the body Il on these plates will not cause 'themto bind to prevent pin 4i from swivelling in opening 30. Due to the simplicity of construction of the device. which is one of the important advantages of the invention, a further description of the operation of the invention is considered unnecessary.

Obviously, various modifications and changes in the construction and arrangement of the parts forming the invention may obviously be made and are contemplated without departing from the principle thereof and the right is reserved to make such variations and changes in the construction and arrangement of the parts as will' not depart from the spirit and scope of the invention as hereinafter dened by the appended claims.
